Phospholes, synthesised by an improved procedure, undergo Diels-Alder reactions at high pressure but not dipolar cycloadditions to nitrile oxides (which deoxygenate) or diazomethanes (which can, however, trap the phosphole oxides). Diphenylketene gives an unexpected spirophosphorane with phospholes at 9 kbar.
